Verify Group Who Owns /etc/nftables Directory

Description

To properly set the group owner of /etc/nftables, run the command:

$ sudo chgrp root /etc/nftables

Rationale

The ownership of the /etc/nftables directory by the root group is important because this directory hosts nftables configuration. Protection of this directory is critical for system security. Assigning the ownership to root ensures exclusive control of the nftables configuration.
